- Water is your body's principal chemical component and makes up about 60 percent of your body weight. Every system in your body depends on water. For example, water flushes toxins out of vital organs, carries nutrients to your cells, and provides a moist environment for ear, nose and throat tissues.

Abundance of the chemical elements The elemental composition of the human body can be looked at from the point of view of either mass composition, or atomic composition. To illustrate both views, the adult male human body is approximately 57% water, and water is 11% hydrogen by mass but 67% by count of atoms (i.e. 67 atomic percent).ie charts of typical human body composition by percent of mass, and by percent of atomic composition (atomic percent). Almost 99% of the mass of the human body is made up of six elements: oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus.

How much salt is in a human body? The human body contains many salts, of which sodium chloride (AKA common table salt) is the major one, making up around 0.4 per cent of the body's weight at a concentration p … retty well equivalent to that in seawater. So a 50kg person would contain around 200g of sodium chloride-around 40 teaspoons.

What is your body worth? (Because of its low atomic weight, even though 63% of the atoms in a body are Hydrogren, this equates to just 10% of the mass of a body). 99% of the mass of the human body is made up of the six elements: Oxygen, Carbon, Hydrogen, Nitrogen, Calcium, and Phosphorus.Because of its low atomic weight, even though 63% of the atoms in a body are Hydrogren, this equates to just 10% of the mass of a body). 99% of the mass of the human body is made up of the six elements: Oxygen, Carbon, Hydrogen, Nitrogen, Calcium, and Phosphorus.

How many atoms are there in a human body? It really depends on the person. As you know, not every person fits to the exact same dimensions, so it would be hard to try to generalize the amount of atoms in the human body. However, I am taking a stab at anyway. There are 37.2 trillion cells in the 'average' human body, and there are 100 trillion atoms in each cell. So that comes out to be about 3 quadrillion 720 trillion atoms in the human body.

Composition of the human body Pie charts of typical human body composition by percent of mass, and by percent of atomic composition (atomic percent). Almost 99% of the mass of the human body is made up of six elements: oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus.Only about 0.85% is composed of another five elements: potassium, sulfur, sodium, chlorine, and magnesium. All are necessary to life.n fact, 90% of the cells in (or on) a human body are microbes, by number (much less by mass or volume).

What elements are the humans made of? Question: What Are the Elements in the Human Body? Answer: Most of the human body is made up of water, H2O, with cells consisting of 65-90% water by weight. Therefore, it isn't surprising that most of a human body's mass is oxygen. Carbon, the basic unit for organic molecules, comes in second. 99% of the mass of the human body is made up of just six elements: oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus.

- The periodic table of elements below is color coded to show the elements found in the human body. Of the elements found in the human body, four of them make up the largest percentage of our body weight (96.2%). The four elements are oxygen, hydrogen, carbon, nitrogen. Before you start thinking we should float away with all the oxygen, hydrogen, and nitrogen atoms, remember that the oxgen molecules are mainly part of the water in our body (H2O).

What Are the 3 Most Common Elements in Human Bodies? Oxygen is the most abundant element in the human body. It makes up 65 percent of the total weight of a person. For a person with a weight of 155, about 94 pounds of her total weight would be made of the element oxygen. This is due mainly to the body's water content.

What Are the Elements in the Human Body? There are several ways to consider the composition of the human body, including the elements, type of molecule, or type of cells. Most of the human body is made up of water, H 2 O, with cells consisting of 65-90% water by weight. Therefore, it isn't surprising that most of a human body's mass is oxygen.
